Abstract
The present invention provides methods and apparatuses for tuning a circularly polarized patch antenna to compensate for manufacturing tolerance variation, and to compensate for mistuning of the antenna due to the implementation of the product in which the antenna is used. Varactors are coupled to the metal patch portion of the antenna, and a dc voltage is applied to tune the antenna capacitance. The varactors can receive different voltages if desired.
